Thiazolo[5,4-d]thiazoles (TzTzs) are fused bicyclic heteroaromatic compounds characterized by a rigid planar backbone and an extended π-conjugated electronic structure. Although they have been known for many decades, interest in their properties and applications has begun to increase only recently, after their incorporation into a series of active materials used in the field of organic electronics. Recently, the thiazolo[5,4-d]thiazole scaffold has been inserted into new photoactive compounds (both small-molecule compounds and polymers) used to build bulk-heterojunction organic solar cells (OSCs), as well as in new organic π dyes for dye-sensitized solar cells (DSSCs). This microreview focuses on the preparation of such TzTz-containing materials and their application in the field of organic and hybrid photovoltaics.

基于噻唑并[5,4-d]噻唑核的光活性化合物及其在有机和混合光伏中的应用

噻唑并 [5,4-d] 噻唑 (TzTz) 是稠合的双环杂芳族化合物，其特征在于刚性平面主链和扩展的 π 共轭电子结构。尽管它们已经为人所知数十年，但直到最近，在将它们纳入有机电子领域使用的一系列活性材料之后，人们对其性质和应用的兴趣才开始增加。最近，噻唑并 [5,4-d] 噻唑支架已被插入用于构建体异质结有机太阳能电池 (OSC) 的新型光活性化合物（小分子化合物和聚合物）以及新型有机 π 染料中用于染料敏化太阳能电池 (DSSC)。这篇微观综述重点介绍了此类含 TzTz 材料的制备及其在有机和混合光伏领域的应用。
